Re: Full TRAP feature support [was: RE: Re: z/OS 3.1 Announcement US Letter]

[Peter Relson]

I agree with most of the sentiments expressed here. But that ship has sailed. 
And it is far from true that every operating system provides support for every 
hardware facility.

Back when TRAP2 and TRAP4 were introduced (about 25 years ago), OS/390 
development (it was pre-z/OS) was not even aware of it. And we were shocked to 
learn that debug tool had implemented to the architecture. I hope we can agree 
that that was not appropriate - the OS should have provided an API and debug 
tool should have used it. Whether that API would have been limited to 
authorized users is a different question entirely.

At this point, nothing is going to be done without a strong business 
justification.

He might have been referring to z/XDC. ColeSoft acquired zDebug many 
years ago, which used TRAP exclusively, and incorporated much of that 
technology into z/XDC.


IIRC, you must use the 0C1/ESTAEX method only once at initial entry. 
After that, you can switch over to TRAP (which is advantageous)...

Re: Full TRAP feature support [was: RE: Re: z/OS 3.1 Announcement US Letter]

[Bernd Oppolzer]

FWIW,

some years ago (maybe 2010), I replaced the breakpoint mechanism in a 
home grown debug tool
written by my customer; the breakpoints were implemented by capturing 
the S0C1 interrupts of hex zero
insertions into the load module instead of real opcodes. I now insert 
TRAP2 instead of hex zero.


So: I know how to do this ... maybe others on this list, too. The 
problem is: to insert the address of the
TRAP handler routine into the DUCT, you need to be authorized. In our 
installation, we created something
like a special "user SVC" to do this (don't know the details, because 
this was done by our systems people).
That is: a special SVC which only allows to "configure the DUCT". I 
wrote the specification, and then the

systems people created the SVC.

All other actions can be done by normal non-authorized code ... this is 
kind of easy. The rest of the debug tool
remained unchanged. The debug tool was much faster after this change, 
because the RTM work involved

by the S0C1 handling is now saved.

This is a very special application, of course, and I never would have 
thought about using TRAP2, if the
debug tool of the customer didn't exist already (since the 1980s, long 
before TRAP2 arrived, which was ca. 2000,
IIRC). But when I learned about the internals of the debug tool (the 
S0C1 mechanism), it seemed
sort of natural to me to think about this TRAP2 replacement. And the 
customer allowed me to give it a try.


If you want to know more, feel free to ask me offline; maybe I remember 
the details after all this time.
The debug tool is still in daily use by the developers at the customer's 
site (for PL/1 and ASSEMBLER programs).


Kind regards

Bernd

Seriously IBM was delivering AC922 or IC922 POWER servers.
POWER machines with NVIDIA GPUs for AI.
However they stopped.
Why?
Because they started delivering its own "AI chip", in z CP or POWER CP.

Is Intel cheaper? NO.
There are plenty of analyses where POWER is economically more effective 
than Xeon.

The same apply to z CP.

I'm not working for IBM (now) and I was never involved in sales. The 
above are just facts.
Of course we knowe sometimes a solution which means a competition is not 
the best. Sometimes it is selled the best.

Traditionally, the business case would have been that a debugging facility
like this led to increased ability to exploit the platform, thus leading to
more usage and more sales. Whether that still applies-whether IBM is
interested in that for IBM zSystems-is unclear. With cloud, cloud, and more
cloud, maybe not so much?

Re: Full TRAP feature support [was: RE: Re: z/OS 3.1 Announcement US Letter]

[Martin Trübner]

I did develop a fully featured debugger solely on TRAP for VSE.

I did that in 2000 as proof of concept or better to show that TRAP is 
not there for "year 200o fix up" as pops did say at that time.



Originally it was object code only in CICS (just to see that it works)- 
meanwhile I support CICS and batch as well as debugging source code.



I am semi retired now- but the tool is still available for free for a 
VSE environment. It supports z-arch including the z14. Because of the 
only use of TRAP to intercept it doe not need to know every instruction.



What I like to say:  pops has everything needed, but a software 
supported API would be great.



I know of one big z/OS installation that has a debugger in use that uses 
TRAP (and the author is on IBM-main as well)



Mentioning software vendors- there is a debugger called z/TDF from Arney 
Software - runs on z/OS and explored TRAP as well.



Chuck is a good friend and I can see/imagine roots of his debugger in 
talks we had (and it is way younger than mine)MINE) during various real 
life meeting (in bars) we had.

One potential business justification for IBM would be "to sell the hardware

Isn't that essentially the business justification for *all* new z/OS features?

provided.

And given the amount of time that has gone by and the fact that, to my 
knowledge, there never has been a formal request/requirement submitted asking 
for such an API, the answer to your question (unless such a requirement is 
submitted) is, in practice, "never".

And a new requirement might be declined unless there is significant business 
justification that would make this a good candidate.

We all wish that we were in a world where "should" would match "it is", but 
there is always a resource tradeoff to be made between competing items and the 
question has to be answered of what would you the customer (and IBM) be willing 
to sacrifice getting in order to get "this". "Should" only takes you so far. 
That should be apparent to all (but many discussions on IBM-Main do not seem to 
take that into account).

Amusing to see how IBM's view of geopolitics plays out. Under  "Regional
availability", the Canadian letter that was first posted has:

Anguilla, Antigua and Barbuda, Aruba, Bahamas, Barbados, Bermuda, Bonaire,
Sint Eustatius and Saba, Canada, Cayman Islands, Curaçao, Dominica, Grenada,
Guyana, Jamaica, Montserrat, Saint Kitts and Nevis, Saint Lucia, Saint
Vincent and
the Grenadines, Sint Maarten, Suriname, Trinidad and Tobago, Turks and
Caicos
Islands, and British Virgin Islands

while the US one has:

American Samoa, Guam, Marshall Islands, Federated States of Micronesia,
Northern
Mariana Islands, Palau, Puerto Rico, United States, and US Virgin Islands

I wonder which of all those island nations/states/territories actually have
even one z machine in service...


That's the question I wanted to ask! :-)

However never say never. I know mainframes in Belize (population <.4M), 
Barbados, Bahrain, Brunei, Estonia, Ghana, Gabon, Estonia, Trynidad & 
Tobago, India...

Oh, maybe India was not good example.

Seriously: things changed a lot with connectivity. I know few dozens 
mainframe "shops" in Poland, however the machine is somewhere else. 
Something like a cloud.

It's my understanding that they are tensor cores, which are a type of 
vector processor optimized for matrix multiplication that can increase 
throughput per cycle. IBM have published the C API spec on Github [1]. I 
suspect they will create a Python tensorflow extension for ML/AI 
exploitation.

Naturally, it's not an AI engine on its own; software is required for 
that functionality. An ACM article [1] suggests that a 32-chip system 
can achieve 200 tflops, which is roughly double the output of a $1500 
NVIDIA GeForce RTX 4090 graphics card with air cooling. In this context, 
low latency is a critical factor.

There is a lot of AI related stuff in the announcement, including a new

integrated AI on die and a C library was published. Does anybody know if
this has been ported to Python numpy or tensorflow?

In z/OS 3.1, AI and analytics solutions such as the following plan to be

Amusing to see how IBM's view of geopolitics plays out. Under  "Regional 
availability", the Canadian letter that was first posted has:

Anguilla, Antigua and Barbuda, Aruba, Bahamas, Barbados, Bermuda, Bonaire, Sint 
Eustatius and Saba, Canada, Cayman Islands, Curaçao, Dominica, Grenada, Guyana, 
Jamaica, Montserrat, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the

while the US one has:

American Samoa, Guam, Marshall Islands, Federated States of Micronesia, 
Northern Mariana Islands, Palau, Puerto Rico, United States, and US Virgin 
Islands

I wonder which of all those island nations/states/territories actually have 
even one z machine in service...
